literature that helps me in my profession
Our mutual profession of business analytics is described in countless books, papers, website and documents. Like you I also struggle to find the ones that really matter, or focus on the subjects I am interested in. Your best friend here is Google. To help you out I listed some of the books that help me every single day. I use them as reference guides and refer to them regurlarly.
The list is my own list and doesn't imply at all there are no good or better alternatives out there.
